Sp503-I-Identifying The Flathead Appletree Borer (Chrysobothris Femorata) And Other Buprestid Beetle Species In Tennessee, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The flatheaded appletree borer, Chrysobothris femorata (Olivier) (FHATB) is a well-documented, native pest of deciduous trees. It has a wide host range and is particularly problematic in commercial nurseries and urban landscapes, where it can cause rapid decline of economically important hosts. When infestations are high, FHATB has been known to attack healthy trees as well as those stressed by drought, plant disease, mechanical injury and other environmental factors. Its distribution is ubiquitous, covering the entire continental United States and extending into Canada.

Sp341-U-The Bagworm And Its Control, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The bagworm, Thyridopteryx ephemeraeformis (Haworth), is one of the more curious and interesting insect pests of trees and shrubs. Its carrot-shaped bag is constructed of bits of material from the plant upon which it is feeding and is enlarged as the bagworm grows. The bag is carried wherever the worm goes. When disturbed, the bagworm merely pulls its head back into the bag for protection.

Sp290-C-Dogwood Borer, Infestation, Damage And Control, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The flowering dogwood (Cornus florida) is one of the most popular ornamental plants in Tennessee landscapes. Native trees also flourish in the forest understory.

The dogwood tree is damaged by the feeding activity of the dogwood borer larva under the bark of the trunk and limbs. In a single year, one borer can completely girdle and kill a tree 4 inches in diameter, but death is more often brought about by the combined activity of several larvae or by successive infestations with concurrent mechanical injury or pathological problems. Cultivated trees growing in full sun are usually more heavily infested than …
